Part 140-922 is a replacement pump cylinder for Commander spray equipment. This precision cylinder houses the piston and forms the pumping chamber where material is pressurized. When the original cylinder becomes worn, scored, or damaged, replacement restores pump efficiency and pressure.

The 140-922 pump cylinder is a direct replacement component for Commander spray equipment. This precision-machined cylinder is the heart of the pumping system, providing the chamber in which the piston reciprocates to draw in and pressurize material. The cylinder's inner diameter is finished to a precise tolerance and surface finish to work effectively with the piston and packings, creating a seal that allows pressure buildup. A properly functioning cylinder is essential for achieving rated pressure, maintaining consistent flow, and ensuring efficient pump operation. A worn, scored, or corroded cylinder can cause loss of pressure, reduced output, excessive packing wear, and fluid leakage past the piston. This replacement cylinder is manufactured to exact specifications for inner diameter, length, and mounting features. The material is selected for durability and compatibility with various coatings. Installation requires careful cleaning and proper alignment with the pump body. Regular inspection during pump overhaul helps identify cylinder wear before it leads to significant performance loss.
